@Daniel: do you have specific projects in mind, or just want to learn the language? Low-level stuff (hardware oriented) versus high-level, like GUI's ... the first would tend to make pointers, arrays, and interrupts more important, whereas GUI's usually need specific Libraries... then there's the stuff in the middle - like database connections, web communications, number crunching ... again the libraries matter.

I like Kdevelop too - and also the QT tools from Troll Tech (because I'm a Troll too )
